Note the BUILD_PYTHON_SUPPORT and PYTHON_EXECUTABLE flags to cmake. In the output to cmake, you should see:

Python: ON
Python interpreter: /usr/bin/python2.6
Python numpy: YES

under “Interfaces:”.

Test the install. Launch Python, and run:

import numpy
import cv

Nothing bad should happen!

(Make sure the “release” directory is nice and clean before you run cmake & make. At one point, my release directory was in some weird state so that after I ran make, “import cv” gave me a segfault. Clearing out the directory and rerunning the install process made everything work!)
